I know this is going to seem somewhat like a troll post, but I pose this as a serious question. Since our human population of this rock is continuing to grow in girth, and people keep trying to see how far skin can stretch there is a new issue arising for self defense. How does one grapple someone who is morbidly obese?? I have been putting some real thought into this question (probably more than I should), but I just can't come up with a way to counter blubber and weight. Would any type of takedown even be effective against someone that huge?? I couldn't see any version of a leg takedown working since it would be like grabbing a tree.

So this is the question I pose to you: how do takedown a morbidly obese person, and what do you do once on the ground to win??

duck under or arm drag, take back, jump up on back get rear naked choke on and hooks in. As fat guy passes out disengage so he does not fall on you.

Adressing the op because I haven't read most of the thread. I started grappling fat, it's really not hard to get taken down when you have so much extra weight pulling you off balance, I found trips especially effective against me. As for on the ground, do you have any idea how much harder it is to keep up and move on the ground when you're fat? I have seen some pretty big guys doing just fine on the ground but most of them will struggle that's why those of us who stick with grappling and were fat tend to lose weight. If you are fitter and are halfway competent you should manage fine.
